Hi,
after modifying the data of a surface node, I looked for a possibility
to update the mapper to render the manipulated data. When using pure VTK
this is possible with the following statements:
pMapper->Modified();
pMapper->Update();
But I can't find something similar in MITK. Isn't there really no
mechanism to update the mapper of a node? Is it really necessary to
create a new surface object like this?
// get surface data
mitk::Surface* pSurface =
dynamic_cast<mitk::Surface*>(pNode->GetData());
vtkPolyData* pData = pSurface->GetVtkPolyData();
vtkPoints* pPoints = pData->GetPoints();
// manipulate data
// create new surface to render manipulated data
mitk::Surface::Pointer pNewSurface = mitk::Surface::New();
pNewSurface->SetVtkPolyData(pData);
pNode->SetData(pNewSurface);
Thanks.
Horst
